Best time

late October–early November

Once a year by the end of October and the beginning of November, the vast area around China's largest freshwater lake is lavishly coated with pink-purple flowers. Polygonum criopolitanum or simply knotweed flowers love the wetlands surrounding Poyang Lake. During the short flowering season, the area attracts dozens of tourists with cameras. Head out to China's south-eastern province of Jiangxi and enjoy the splendour of pink sea of flowers.
